I needed an electric brake controller and installed on my vehicle and Matt was great. He helped me choose the right controller for my Jeep and ordered all the correct parts and harnesses so I didn’t have to worry about it ordering the wrong parts. It was very professionally installed; nice and clean. Thank you Wieland’s Auto!!! Highly recommended.
